Saturday morning, however, I decided to take advantage of the 10 a.m. park ranger-guided tour in Jean Lafitte National Historical Park swamp about a half hour away. A surprising number of others were waiting at the trailhead, apparently with the same need to get out into nature but under some shade. The ranger took us on a trail I'd already experienced but without the narrative. I learned a few new things.
The first stop on our tour was a shell mound, basically the garbage dump of early native Americans, but minus the styrofoam and plastic bottles. They ate a lot of freshwater clams as well as crawfish, catfish and perch. We moved from hardwood forest to swamp and marsh and then into an open area where a canal had been dug to move cypress logs and when those were all gone, oil.
